PATENT LOOM.

SPECIFICATION forming part of Letters Patent No. 237,585, dated February 8, 1881.

Application filed May 25, 1880.

To all whom it may concern Be it known that I, GEORGE L. PALLATT,

a citizen of the United States, residing in the city and county of Philadelphia, and State of Pennsylvania, have invented a new and usel'ul Improvement in Looms, which improvement is fully set forth in the following specification and accompanying drawings, in which Figure 1 is a front view of the loom embodying my invention. Fig. 2 is a side elevation thereof. Figs. 3 and trepresentdetail sectional views of some of the-devices for operating the harness-frames. Fig. 5 is a horizontal section, enlarged, on line 3 y, Fig. 1, the harness being also removed and a portion of the lay cut away. Fig. 6 is a face View of oneof the cams which operate the picker-sticks. Fig. 7 is a vertical section in line 2 2, Fig. 5. Fig. 8 is a rear view of a portion of the lay, showing the springs with which the shuttle engages.

Similar letters of reference indicate correspondin g parts in the several figures.

My invention consists of certain new and useful improvements in looms more especially designed for weaving ribbons or other narrow goods, as will be hereinafter fully set forth in the claims.

Referring to the drawings, A represents the frame of the loom, and B the main shaft, on which latter is loosely fitted an eccentric, O, and a concentric toothed wheel, D, the eccentric C and concentric wheel D being connected or formed as one and adapted to receive power from the shaft B by means of a clutch, B, on said shaft, the lever B whereof is conveniently accessible. The said clutch is a sliding collar adapted to engage with said wheel D, and the lever B is a shipping-lever, which may be operated horizontally to throw said clutch into or out of said engagement at will.

Meshing with the wheel D is a toothed wheel, E, whose shaft E is mounted on the frame A, above and parallel with the shaft B, and carries a wheel, F, having a cam-groove, a, into which projects a stud or roller, b, at thelower end of a verticallyarranged rod or arm, G.

Pivoted to the rear of the frameA is alever or arm, G, whose upper or inner end is pivoted to the lower end of the rod G, the connecting-pivot carrying the stud or roller 1), and the lever or arm G acting as a guide for keeping the stud or roller bin position in the cam- (No model.)

groove a. The arm G is longitudinally slotted at its connection with G, and said slot receives a pivot-block, whereby such connection is made. By moving said block forward or backward in said slot the throw of the arm G may be adjusted with accuracy with relation to the cam-groove a of wheel F.

On a frame, A, at the upper part of the frame A, is mounted a vertically-sliding carriage, H, which receives motion by means of a curved slotted arm, J, working on a stud or roller, J, on the carriage, and connected to a rocking shaft, J, mounted on the frame A, said shaft having fixed to it an arm, (I, which is connected to the upper end of the rod G.

Pivoted to the rod G is a pawl, K, which engages with a ratchet, L, whose shaft 0, mounted on the frame A", carries a pinion, f.

On the frame A are mounted two horizontal cam-shafts, M, whose ends carry pinions g g, geared together, and one of them gearing with the pinion 7.

To the said sliding carriage H there are secured cross-bars N, which extend parallel with, and are located above, the cam-shaft M, and are adapted to be engaged by the upper hooked ends, h, of rods P of the harness or shedding mechanism,the frames Q whereof are suspended from said rods P, the latter being guided in the bottom cross-piece of the frame A.

The upper portions of the rods P are elastic, their tendency being to cause the hooked ends h-to move from the cross-bars N, while said portions are so disposed in relation to the camshafts M that they are pressed by said shafts toward the cross-bars N.

The shaft 6 of the ratchet L and gear-wheel f, having an intermittent motion, carries or has formed with it a squared or four-sided portion, 0, against which pressesa spring 6, it being noticed that the ratchet L has four teeth, so that whenever said ratchet makes one-quarter turn the spring 6 stops the motion of the shaft 6, and consequently of the gearin g f g g and rotary cam-shafts M M.

R represents horizontally-arran ged pickin gsticks, Which are adjustably connected to heads R, which are pivoted to proper portions of the frame A, and receive positive motions forward and backward by means ofcam-wheels S, fixed to the shaft E.

' Each cam-wheel S has a bulb or swell, s, and

a cam-bead or flange, s, Fig. 6, arranged so that when the wheel makes a part of its rotation said bulb presses against the end of the head It of one picking-stick and vibrates said stick in one direction and as the said wheel makes the remainder of its rotation the said head presses against the front part of said head and vibrates said picker-stick in the other direction, thus completing the operation of the stick, both motions being positive. The heads B have sockets to receive the ends of the picking-sticks and set-screws k for permit ting the adjustment of the sticks, as more readily seen in Fig. 5, so that the sticks may be set with nicety relatively to the lay and shuttle, and, in the eventof breakage, removed and fresh sticks applied. The sticks R pass through horizontal guides 1, which are supported on the frame, and are of curved or angular form. The inner ends of each pair of guides T support the guides Q, of the harnessframes Q, the grooves k for the reception of said harnesses being shown in Fi 5, theharnesses being removed.

U represents the lay, and U" the shuttle, which is fitted thereto by a tongue and groove or other connection, and adapted to be struck alternately by the two sticks It t when the lay is advanced. The lay has connected to its lower end a ball, T, which is fitted in a socket, T, consisting of hemispherical shells bolted together and secured to the upper limb of an elbowdever, V, whose shaft is connected to thelower portion of the frame A. The lower limb of the lever V is pivoted to an arm, V, of

the strap V of the eccentric (J, so that thelay is operated by the eccentric 0 through the intermediate mechanism V V V. The socket T" is provided with set-screws or bolts m for holding the ball T in position, it being noticed that byloosening said screws or bolts the ball may be moved or turned and the lay then nicely adjusted in many directions relatively to other parts of the loom, after which the screws or bolts are tightened and the lay retains its adjusted position.

A number of looms may be placed side by side and the drivingshat't B extended so as to render service common to all. The guides T of all the looms may also be connected so as to assist in steadyingand bracing the looms.

It will be seen that when the loom is set in motion the lay and picker-sticks are operated and rising and falling motions imparted to the rod G. The motions of the slotted arm J raise and lower the carriage H, and the pawl K rotates the ratchet L, thus imparting intermittent motion to the gearingfgg, and, consequently, to the cam-shafts M M.

It will be noticed, referring more particularly to Fig. 3, that the cam-shafts are really elliptical in cross section, and their arrangement in operative positions is such that the flat or longest side of one shaft is at a right angle to the flat or longest sideof the other shaft. Consequently, when the carriage lowers one shaft presses against one of the rods P, while the other shaft is free from the other rod. The rod thatispressedis placedin such position that when the carriage rises the hooked end of said rod is caught by the cross-bar N that is above it. Consequently said rod is raised, and with it the respective harness-frame Q. When the carriage lowers, said rod, owing to the quarter-turn of the cam-shaft, is relieved of said shaft, and the rod, being elastic, clears the cross-bar and remains passive. The other rod has been meanwhile pressed by its respective cam-shaft, placed in position, caught by its cross-bar, and elevated, and the relative harnesstrame raised. The carriage lowers and the rod last described is released similarly to the first-named rod, the latter being again placed in position and operated, the alternate operation of the two rods being continued.

On the opposite sides of the rear of the breast-beam of the lay are secured horizontally-arranged springs W, which are so disposed that when the shuttle has about made its full throw on each side its back portion (which is cut away or has an offset) rides over a spring and tightens thereagainst, so that the shuttle remains perfectly at rest until struck by the picking-stick.

The number of liariiessframes may be increased, in which case the carriage will be provided with a corresponding number of cross bars N, and the frame A with additional camshafts M, the goat-wheels whereof mesh with the gearing g or g.

Having thus described my invention, what I claim as, new, and desire to secure by Let ters Patent, is-

l. The lay provided with an adjustment consisting of a ball-and-socketjoint, substantially as and for the purpose set forth.

2. The combination, with the picker-sticks, of a supporting-shaft and apair of wheels or disks mounted thereon and provided with raised cam-beads s and bulbs s on their outer surfaces, said cams acting directly upon the stocks of said picker-sticks, substantially as set forth.

3. The picking-stick guides T and the guides Q for the harness-frames supported thereby, in combination with the picking-sticks, harness, and operating mechanism, substantially as set forth.

4. The combination of elastic rods 1 P with shafts M, elliptical in cross-section, the sliding carriage, and operating mechanism, substantially as set forth.

5. The earn-shafts M, gearing ggf, 'atchet L, and pawl K, in combination with shaft 0, having an angular portion, 0', and the spring 0, substantially as and for the purpose set forth.
